VDP: the new VDR in vSphere 5.1

29 August 2012
Comments off

Reading Time: 3 minutesIn the new vSphere 5.1, there is a missing component replaced by a new one: VMware Data Recovery (VDR) has been replaced by the new VMware vSphere Data Protection (VDP). VDR was a backup solution introduced with vSphere 4.0 and based on the VMware vSphere API for Data Protection (VADP) which includes the Changed Block Tracking (CBT) technology (to have incremental backup). But was a limited product (especially not suitable to scale to with several VMs) and also the 2.0 version introduced in vSphere 5.0 was not so changed too much (except in a little […]

Issue in VM migration: MAC Address may change

22 August 2012
Comments off

Reading Time: 2 minutesRecently I got a strange issue using a cold storage migration usign the Migrate function of vCenter Server. This was the scenario: a Free Hypervisor with some VMs where a full license (Essential Plus) was added and the host was also added to a vCenter Server. For compatibility matrix reason the version 4.1 was used (although the storage can work with vSphere 5.0 but officially was not supported). Also the Free Hypervisor was build with the 4.0 version and upgraded (one year ago) to the 4.1 version. This was the issue: after a cold storage […]

Reading Time: < 1 minuteSome months ago I’ve realize a course for the Backup Academy titled: Basic principles of backup policies. Now it’s available also a whitepaper title “Backup policies defined for VMware VMs” (but it’s enough general to be applied for generic policies, both for physical and virtual environment). This is the list of all the media type available on my course: Online video with transcript Offline video Podcast PowerPoint Slide Whitepaper

NexentaVSA for View: Usage

10 August 2012
Comments off

Reading Time: 5 minutesIn the previous posts we have discuss about the architecture and the deployment of NexentaVSA for View. Has you have probably notice the configuration of NexentaStor VSA is really simple: just an OVF deploy, a test to verify that all is fine and a convert to template to be used during virtual desktop pool deployment. Now let’s talk about how use this product, that it’s well described in the User Guide and also in this video. As written in the previous post, the management appliance could be controller with a simple browser (Mozilla Firefox v9 […]

NexentaVSA for View: Deployment

9 August 2012
Comments off

Reading Time: 4 minutesIn the previous post I’ve described the NexentaVSA for View architecture and the files included in the download packages. The deployment, installation and configuration is not a simple and immediate step, but is well described in the Installation Guide and also on this video. There are several requirements for the vSphere datacenter (the NexentaVSA for View environment requires a separate datacenter for each ESXi cluster), the VMware cluster (the NexentaVSA for View environment requires at least one ESXi cluster that contains one or more ESXi hosts, but must also be an empty cluster or are […]

Comments off

Reading Time: 4 minutesIn the previous post I’ve introduced the main characteristic of NexentaVSA for View. Now let’s give more detail on the architecture of this solution. The overhall architecture is well described on the NexentaVSA VMware View HW Reference Guide (that include also some interesting sizing scenarios). In a local storage storage approach we will have the following components: NexentaVSA for View Management Appliance: provides the NexentaVSA for View management functions. The Management Appliance is installed from an included template and can be located on any ESXi host in the network. NexentaStor VSA: is a virtual storage […]

NexentaVSA for View: Introduction

7 August 2012
Comments off

Reading Time: 4 minutesNexentaVSA for View (NV4V) is a solution developed by Nexenta, with the collaboration also of VMware, that implement an integrated virtual storage solution for VMware View deployments and provides a interesting approach to VDI implementation. It tried to solve most of the possible issues or disadvantages of a VDI approach: Performance: in common VDI environment the storage could become the bottleneck of the infrastructure, with this solution you can simple scale by adding new hosts (in the same way on how you can scale to add more computational power). Cost: it remove the need of […]
